Description
Technical field
This patent belongs to Karst Rocky Desertification Region vegetation and ecological environment reconstruction works technical field, relate to the reclamation and the soil and water conservation method in the karst landform zone of degeneration, particularly utilize the macromolecule resin with water and soil conservation function of trace, the clay in karst landform zone, humus soil and peat component improve the soil of Karst Rocky Desertification Region, to prevent the loss of water soil, help the method for vegetation recovery.
Background technology
For a long time, in most karsts, the artificial disturbance because firewood is adopted, herds, burnt the grass on waste land etc. causes vegetation to destroy repeatedly, the vegetation resources scarcity, ecological environment frailty, frequent natural calamity, soil layer is more shallow, soil erosion is very serious, rock exposed rate in some areas increases year by year, has caused that the stony desertification phenomenon is on the rise, and causes very difficulty of vegetation recovery.Although enrich at karst zone same season of hydro-thermal, precipitation, but owing to distribute uneven in the basin in amount of precipitation year, soil layer is shallow, the soil body is discontinuous, and characteristics such as the soil water retention capacity is low, seepage is serious, easily cause the soil seasonal drought, even in rainy growth season, the dry period of evaporation capacity greater than amount of precipitation also often occur, this affects the recovery of vegetation to a great extent.Especially in the long-pending bigger stony desertification location of higher, the naked scar of degree of degeneration, vegetation system is very fragile, and the ability of the anti-external interference of group is very low, and the back self-repairing capability of being damaged is poor, and the difficulty of recovery naturally of habitat and vegetation is very big.Habitat after destroyed and vegetation not only are difficult to nature and recover, and have caused serious vicious circle, make constantly to take place the annual more and more serious catastrophic natural calamity that all has such as landslide, mud-rock flow etc.
Tang Kai, He Min is in " Guizhou karst mountain area technology for recovering vegetation measure " (shelter-forest science and technology, 2007,78 (3), 141-142) spoken of two kinds of main paties of karst vegetation recovery in the literary composition: the one, artificial afforestration, destroy thoroughly, the degree of depth is degenerated, soil is less, recover the less location of potentiality naturally carries out soil moved in to improve the original and afforest; The 2nd, close hillsides to facilitate afforestation, to not taking the location of artificial afforestration,, adopt the mode restore vegetation of closing hillsides to facilitate afforestation as various niches such as stone face, crack of stone, stone ditches.Woman's bow thread etc. is " the ecological environment characteristics and the technology for recovering vegetation of Karst Mountain Areas in the Guizhou Province " (Nanjing Forestry University's journal (natural science edition) at exercise question, 2003,27 (1), the measure of the recovery of the vegetation specialized has been proposed: protection of (1) inferior woods and rejuvenation measure in 45-49); (2) manually promote the natural regeneration measure; (3) the conceding the land to forestry measure that settles at one go; (4) the vegetation recovery measure that retreats of first woods; (5) safeguard measure of the compound operation measure of self-employed tree cultivator and (6) forest cover etc.; In patent CN1596608A, also spoken of the method for recovering karst mountain area degeneration vegetation ecological system; this method is to gather the seed of chief species in the woods season at seed maturity; soil is arranged in selection and the vacant lot do not had on the karst mountain area of degeneration of arbor is broadcast into seed; in the mountain village, form the mechanism of managing and protecting accordingly, with the normal sprouting of protection seed.Wherein managing and protecting mechanism accordingly is exactly to avoid people and animals to trample on.Deng Xinhui, Jiang Zhongcheng is at article " the karst effect of Larsen forest vegetation is done in Guangxi " (earth and environment, 2007,35 (2), 128-133) speak of in the literary composition Guangxi do to draw closed hillsides to facilitate afforestation more than 40 year after vegetation to the good influence of atmospheric precipitation, top layer karst spring physicochemical characteristic, soil natural water content and the soil water.But apart from the Dong Wang that does to draw less than 2km, lithology is similarly dolomite, but the recovery situation of vegetation is different, and Dong Wang closed hillsides to facilitate afforestation since 1984, and what form now is shrubbery based on five-leaved chaste tree etc., vegetation coverage 65%, and rock exposes the rate height.It is a reasonable special case of closing hillsides to facilitate afforestation and managing that Guangxi does to draw, but, resource huge serious deficient today at scientific and technical high speed development, population pressure, the ecological environment that needs the karst zone that 40 years years recover to degenerate, obviously recovery process is long too for a long time, recovery management not only needs huge human and material resources and financial resources input, and the technical difficulty of management is also very big.In addition, for those are thorough destruction, the degree of depth is degenerated, soil is less, recover the less location of potentiality naturally, the method of carrying out soil moved in to improve the original afforestation is also somewhat single, because several rainfalls, the soil moved in to improve the original of bringing is run off totally, especially experienced destruction repeatedly in those vegetation, soil layer is shallow, severe water and soil erosion, the serious area of stony desertification.In fact, vegetation, soil and moisture be in the karst ecosystem three have be mutually related, important and responsive factor of natural environment.Wherein soil and moisture are the bases of vegetation sustainable development, only had suitable vegetation fast, the soil and the moisture of stable growth, vegetation could recover in a short time, and the root system of the vegetation that has recovered has the function of fixing soil, from then on just can enter the benign cycle of vegetation recovery.Obviously, the karst regional soil of improvement stony desertification reduces soil erosion, and particularly increasing its water-holding capacity, increasing its water retaining function and improve its ability that adapts to plant growing is most crucial and crucial technology in the stony desertification karst mountain area vegetation recovery measure.
Summary of the invention
The purpose of patent of the present invention provides a kind of soil, minimizing soil erosion that improves stony desertification karst zone, increase its water retaining function and improve the ability that it adapts to plant growing, the vegetation in the karst zone of having degenerated can be recovered expeditiously, promote the method that vegetation recovers rapidly.
